Solution

1. Preparation

• Gather tools and parts needed.

• Disconnect the battery if any electrical components are involved.

2. Inspect and Replace Seals

• Sub-steps:
  1. Remove any panels covering the trunk seals.
  2. Inspect the condition of the rubber seals; look for cracks or deterioration.
  3. Clean the sealing surfaces with a suitable cleaner.
  4. If damaged, replace the trunk seal with a new, OEM part.
  5. Apply a weatherproof adhesive if necessary for improved sealing.

3. Check and Seal Tailgate and Rear Lights

• Sub-steps:

  5. For the tailgate, visually inspect and adjust the latch and hinges to ensure proper alignment.

4. Clear Drainage Channels

• Sub-steps:
  1. Locate the drainage channels near the trunk area (usually near the tailgate).
  2. Use compressed air or a small brush to clear any debris or blockages.
  3. Ensure that weep holes are unobstructed to allow proper drainage.

5. Inspect and Seal Rear Window

• Sub-steps:
